MOTOR-BGAT.

. Specification of Letters Patent.

Patented-Dec. 19,3911.

To all whom it may concern.

Be it known that I, Anorsws NIEMC-ZURA, a subject of the Emperor of Austria-Hungary, residing at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Motor-Boats, of which the when occasion so requires, the plane further constituting a cover for the occupants of the boat.

Further objects of the invention are to provide a motor boat of the class referred to, which is comparatively simple in its construction and arrangement, strong, durable, eflicient in its use, and comparatively inexpensive to manufacture.

\Vith the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown the prcferre embodiment of the invention, but it is to be understood thatchanges, variations and modifications can be resorted to which come within the scope of the claim hereunto appended.

i In the drawings, wherein like reference characters denote corresponding parts throughout the several views-Figure 1 is a longitudinal sectional view of a motor boat in accordance with this invention; Fig. 2 is a, plan with the plane broken away at its rear end, and Figs. 3 and 4 are, respectively, a side and rear elevation broken away of the adjusting means for the plane.

Referring to the drawings in detail, 1 denotes the body of, the boat provided interiorIy with a seat 2 and having pivotally connected to the stern thereof in any suitable manner a. rudder 3. The foregoing elements shifted to the position as shown in dotted may beof any suitable construction.

- Arranged in proximity to the stern of the the bottom 8 of the body of the vessel. The shaft 6 projects rearwardly from the hearing 7 and has fixed thereto a bevel gear 9 which meshes with a bevel gear 10 fixed upon a vertically disposed propeller shaft 11. The shaft 11 is su )port'ed in a bracket arm 12 which projects rom the stern of the vessel and is formed with a bearing collar 13 through which extends the shaft 11.

The reference character 14 denotes a hearing for the upper end of the propeller shaft which has projecting therefrom a pair of inclined arms 15 having their outer ends fixed to a pair of vertically disposed posts 16 which are secured at their lower ends to the side of the body of the vessel near the stern of the latter.

Arranged at the bow of the body of the vessel is a pair of vertically disposed tubular members 1 in which telescope a pair of uprights 18, each having its lower end formed with a rack 19 adapted to be engaged by a toothed wheel 20. mounted upon a shaft 21, journaled in a pair of rearwardly extending arms 23 formed integral with the tubular member 17. The member'l? is formed with an opening 22 through which extends the toothed wheel 20 so that the latter will engage with the rack 19. The shaft 21 is operated by a handle or crank 24 and by such arrangement it is obvious that when the shaft 21 is operated in onedirect'ionthe uprights will be shifted upwardly and'when operated in the other direction will be shifted downwardly. To prevent movement of the wheel 20 after it has been rotated to adjust an upright a circular toothed rack 25 and a pivoted dog 26 is provided. The rack is carried by the shaft 21 and the dog by a rearwardly extending ing 27 on the memher 17.

Pivotally connected to the upper end of fthe posts 16, as at 28, is the rear of a rectangular plane 29 and the latter is pivotally connected at its forward end, asat 30, to the uprights 18. The function of the plane 29 is to assist the travel of the boat when the plane is shifted to the position shown in dotted lines, as at 31, Fig. 1, and to retard the travel of the boat when the plane is lines 32, Fig. 1. The plane 29 is of such width and length as to provide a cover for the occupants of the boat.

/Fixed to the propeller shaft 11, near 'the top thereof, is a series of propeller blades 33 which, when the shaft 11 is revolved, are carried therewith and drive the boat, as is obvious.

What I claim is A motor boat comprising an aerial propeller, a vertically disposed propeller shaft, operating means for the propeller shaft, a pair of posts arranged at the stern of the moat, a hearing for the upper end of said shaft, supports for said bearingeonnected to said p0sts,a pair of vertically disposed tubular members at the bow of the boat, a pair of uprights telescoping in said members, means carried by said members and en aging in said uprights for vertically ad ust ing them, means for maintaining the upplane to the top of said posts, and means for i pn'otallyconnecting the forward end of said plane to the top of said uprights, said plane I of a width greater than the width of the boat.

in testimony whereof I affix my signature III the presence of two witnesses.
